Extension Pesticide Program. Host - A plant or animal on or in which a pest lives. Juvenile hormones - Natural insect chemicals that keep the earlier stages of an insect from changing into the normal adult form. Labeling - The pesticide product label and other accompanying materials that contain directions that pesticide users are legally required to follow Mycoplasmas - The smallest known living organisms that can reproduce and exist apart from other living organisms. Nematodes - Small, usually microscopic, eel-like roundworms. Non target organism - Any plant or animal other than the pest that is being controlled.
About biological control
Growers want to control pests and diseases to get maximum production and prevent crop loss. Prevention of pests and diseases before any damage is done is most desirable. Four common methods of control of pests and diseases are biological, cultural, chemical, and integrated control. Predator insects feed on the pests and can control their numbers. There are some parasites that live part of their life inside plant pests and finally kill them.
Pest and Disease Management
In a natural ecosystem, plants are continuously being attacked by all kinds of pests and pathogens such as insects, fungi and bacteria. In the natural ecosystem plants can survive thanks to the help of natural enemies of these unwanted pests and pathogens. In this way, population developments of all players in a natural ecosystem are controlled. But compared to nature, cropping systems are less stable due to human interferences.
Biological control or biocontrol is a method of controlling pests such as insects , mites , weeds and plant diseases using other organisms. It can be an important component of integrated pest management IPM programs. There are three basic strategies for biological pest control: classical importation , where a natural enemy of a pest is introduced in the hope of achieving control; inductive augmentation , in which a large population of natural enemies are administered for quick pest control; and inoculative conservation , in which measures are taken to maintain natural enemies through regular reestablishment.

Biological control is an environmentally sound and effective means of reducing or mitigating pests and pest effects through the use of natural enemies.
Biological pest control
Plant diseases need to be controlled to maintain the quality and abundance of food, feed, and fiber produced by growers around the world. Different approaches may be used to prevent, mitigate or control plant diseases. Beyond good agronomic and horticultural practices, growers often rely heavily on chemical fertilizers and pesticides. Such inputs to agriculture have contributed significantly to the spectacular improvements in crop productivity and quality over the past years. Today, there are strict regulations on chemical pesticide use, and there is political pressure to remove the most hazardous chemicals from the market. Additionally, the spread of plant diseases in natural ecosystems may preclude successful application of chemicals, because of the scale to which such applications might have to be applied.
This book provides recent contributions of current strategies to control insect pests written by experts in their respective fields. There are several other chapters that focus on insect vectors, including biting midges as livestock vectors in Tunisia, mosquitoes as vectors in Brazil, human disease vectors in Tanzania, pathogenic livestock and human vectors in Africa, insect vectors of Chagas disease, and transgenic and paratransgenic biotechnologies against dipteran pests and vectors. This book targets general biologists, entomologists, ecologists, zoologists, virologists, and epidemiologists, including both teachers and students.

PDF | Among all the crops, the total loss due to the pests varied for each control weeds, sometime plant disease agents and insects are used.
This segment includes several paragraphs with general information about biological control and these subsections:. Biological control is a component of an integrated pest management strategy. It is defined as the reduction of pest populations by natural enemies and typically involves an active human role. Keep in mind that all insect species are also suppressed by naturally occurring organisms and environmental factors, with no human input. This is frequently referred to as natural control.
